Question

A cricket ball of 0.5 kg is moving with a velocity of 100 m/sec. The wavelength associated with its motion is: (A) 1/100 cm (B)  6.6× 10-34m  (C)  1.32× 10-35m  (D)  6.6× 10-28m

From de Broglie equation: λ =(h/m upsilon ) =(6.62 × 10-34/0.5 × 100) =1.32 × 10-35 m

Q. A cricket ball of $0.5 k g$ is moving with a velocity of $100 m / sec$ . The wavelength associated with its motion is:

$1/100 c m$

$6.6 \times 10^{- 34} m$

$1.32 \times 10^{- 35} m$

$6.6 \times 10^{- 28} m$

From de Broglie equation:
$λ = \frac{h}{m υ}$
$= \frac{6.62 \times 1 0 ^{- 34}}{0.5 \times 100}$
$= 1.32 \times 1 0^{- 35} m$
